Asks JC-B to return copy of Duchenne [Mécanisme de la physionomie humaine (1862)] and sends some notes "as your former notes were of such extreme interest to me".

Thanks CD for copy of Origin.

Encloses extensive, but incomplete, notes on expression among the insane, dealing specifically with blushing and the actions of the platysma and grief muscles.

JC-B’s essays are the fullest CD has received. His observations on blushing closely agree with James Paget’s. Platysma and horror: Duchenne’s statement doubtful.

Copy of Duchenne [see 7089] has not arrived; CD is concerned that it may be lost.

Returns copy of Duchenne (found in cupboard) with notes [see 7221].

Sends photograph of woman patient with hair standing on end.

Comments on various figures [in Duchenne’s Mécanisme].

Duchenne [Mécanisme] has arrived. Has been testing the photographs with 20 or 30 persons; when all or nearly all agree with Duchenne, CD trusts him. Not one understood the "contracted pyramidal of the nose". CD does not think the so-called muscle of lasciviousness worth exhibiting.

His MS [of Descent] is so large he may print only what he has, and make a second volume of what he is now writing on expression.

Discusses photographs he would like to have: baby screaming, person in paroxysm of fear.
